If you have difficulty with any of these topics, review your notes from prior classes. You can also

look on the internet for tutorials on specific topics on websites such as www.purplemath.com,

www.wtamu.edu/academic/anns/mps/math/mathlab, www.math.armstrong.edu/MathTutorial, or any

other websites from you preferred search engine. Be persistent and resourceful until you find a tutorial

that is helpful, understandable, and provides good examples with answers for you to follow. Don’t

accept just “getting an answer” as it is important that you understand how to successfully complete

these types of review problems.

If you are still having questions about any of the above topics, please ask your teacher for assistance

when school begins.
